udev is a runtime dependency only...

... so you do not need to depend on it here, just in the Config.in file.

And even if you needed to depend on udev at runtime, that's not eudev
you'd have to depend on, but just 'udev' (which is a virtual package
provided by either eudev or systemd.)

Better to patch it out, since we do not keep the documentation on the
target anyway.
